英文摘要	Purpose As micronutrients are essential for all living organisms, their availability in forest soils is important to the forest ecosystem. Studying the effect of global warming on the availability of mineral elements is more significant for forest management, but the scarcity of these elements is a concern. This study aims to investigate the responses of soil micronutrient availability to experimental warming in two contrasting forest ecosystems in the Eastern Tibetan Plateau of China. Materials and methods Using the open-top chamber (OTC) method simulates the global warming and chemical extractants extract soil micronutrients (CaCl2 and Mehlich-3 extractant for Fe, Mn, Cu, Zn, and with boiling hot water for extracting B) to study the availability of these micronutrients in two contrasting forest ecosystems (a dragon spruce plantation and a natural forest) under experimental warming. Results and discussion The results showed that soil temperature in the OTCs was increased by 0.56 and by 0.55 degrees C in the plantation and the natural forest, respectively. The total and Mehlich-3-extractable Cu, Fe, Mn, and Zn were increased by warming in the plantation (except Mehlich-3-extractable Fe, which decreased slightly) but decreased by warming in the natural forest. The CaCl2-extractable micronutrients were not significantly affected by warming. The retained total B in both the plantation and natural forest was decreased by experimental warming. Either the effect of warming or forest type on these micronutrients varied due to their different associations with soil properties. What is more, the relative impact of forest type was stronger than warming on the soil properties with exception of the soil pH and total B concentration. Conclusions Reforestation would generate greater influences on soil environment although it is an important effective action to remain ecologic balance usually. The responses of the total soil micronutrients and their availability to warming depended on the forest type, as their concentration was significantly correlated with the soil water and pH. It was implied that the soil pH and water content are important to the availability of micronutrients in soil and provide managers with important information to better manipulate their forests for tree growth and as wildlife habitats.
